MODERN PUSH BUTTONS AND SIGNALING DEVICES UP TO IP69K W ith Sirius Act Push Buttons and Indicator Lights from Siemens, users can choose from four different design lines to suit particular tastes and requirements, including plastic, plastic with metal front ring, shiny metal or matte metal, flat.

common applications. Compact form is available for some units, i.e. the electronic circuitry is pre-assembled so that user do not need to order the holder, contact module or LED module as separate items. Customised configurations can then be created (spe- cial lockings, enclosure configurations, inscriptions) us- ing the intuitive SIRIUS ACT configurator (siemens.com/ sirius-act/configurator). A key characteristic of these rugged, high-quality products is their ease of assembly with numerous advantages for the user: • Innovative snap-on concept: All components snap on without the need for tools – even in a slanting position; integrated lever for release. • Easy removal: Simply press the release lever to remove the holder. • Simple installation: Fast fixation on the plate with a screwdriver (no special tools needed). • Visual mounting Indicator: Align the arrows to correctly mount the components. • Stacking contact blocks: Up to three modules can be plugged together side-by-side, each with two contact blocks plugged onto one an- other. • Groove-free milled hole: Easy insertion of components without aligning anti-twist lugs. • Easy-to-see module slots: Fault-free connec- tion of modules even when contact blocks are stacked. • 100% twist prevention: Twist-proof holding by screw fixation even if the hole is not perfectly milled. • Sirius Act standard units become communi- cation-capable devices by snapping commu- nication-capable terminal modules onto the standard holder and using them together with a standard or safety interface module. Installa- tion is easy, no special tools are required, just a screwdriver. DMMs FOR WHEN UPTIME MATTERS FLUKE’S 177 and 179 digital multimeters can be found on more tool belts, finding more problems, than any other comparable test tool. With their pre- cision, reliability and ease of use, the 177 and 179 are the preferred solution for professional techni- cians worldwide. Each design is tested for drop, shock and humidity, and is independently tested for safe use in CAT IV 600 V/ CAT III 1000 V envi- ronments. Available from Comtest, the DMMs give users accurate measurements; consistent, reliable performance; attention to safety; and are backed by a lifetime warranty. They measure twice as fast as other multimeters and offer all the features us- ers need to troubleshoot and repair electrical and electronic system problems, in the harshest indus- trial situations. The 177 and 179 offer True-RMS voltage and current measurements, 6 000-count resolution, manual and automatic ranging, and provide frequency, capacitance, resistance, continuity and diode measurements. In addition, they feature 0.09 % basic accuracy, a digital display with analogue bar graph and backlight, and the 179 model includes temperature measurements. Enquiries: lvswitchgear.za@siemens.com

There is complete freedom of choice, as one orders the actuator, the holder and the LED/contact module as separate items. The freedom to combine products ensures maximum flexibility, as resellers can stock them individually as required. Sellers and contractors quote just one article number to order all three of the elements needed to create a functional unit. This helps to save time, effort as well as money when ordering products for
